Construct Psychology devised by Psychologist George Kelly which was used to understand the way in which an individual employs his/her own experience in order to make sense of the world. Kelly Grid also known as a Repertory grid identifies and maps the interactions between the key ideas, themes or constructs that a person uses. These constructs can often be employed to rate or describe brands or organisations in a market research context . This is an individual technique and does not work well in groups .
brain injury is associated with less impairment and better recovery of functions than injury occurring later in development . Subsequent clinical and experimental studies have not fully supported this principle.
